 Converts the image to a platform-specific bitmap object. This has to be done
 to actually display an image as you cannot draw an image directly on a window.
 The resulting bitmap will use the colour depth of the current system which entails
-that a (crude) colour reduction has to take place. Especially when converting
-to 8-bit (or even less) bitmaps, the routine is slow and will reduce the
